Application ined may 1e,

rlhis invention relates to steam traps for use in connection with steam generating apparatusand particularlyin connection with steam separators which are used tor puritying the steam otpoiver boilers. @ne ot the objects orn the invention is to provice tor disposal ot condensed steam or other Waste ivater in a more effective manner and so that the size ot the apparatus may be materially.reduced, or, ith similar apparatus, the capacity thereoi may be materially increased.

Of the accompanying drawings F ig. 1 is an elevation ot a steam separator mounted in a boiler together With a steam trap and the connecting pipes; Fig. 2 is a sectional View along the line 2 2 ot' Fig. 1; and Fig. 3 isa materially reduced elevation ot a separator of several sections mounted in a boiler.

Although my invention applies to the disposal ot condensed Water or other Waste Water, with any apparatus Where a steam trap or other liquid receiver is used, yet for the purpose of illust-rating the invention l prefer to shov.' it as applied to a steam sepl arator anc a steam trap to receive the condensate or separa-ted Water. The separator 10 is mounted in the usual manner in a boiler 11 and it comprises the banks ot baiiies 12 which may be ot any suitable nature, it being understood that the steam trom the boiler passes through'the baiHes into an outlet 13 ot the separator and thence to the steam main 14 outside ot the boiler. As the steam passes through the baiiies the entrained Water tloivs downwardly on the Walls ot the vertical baes into a passageway 15 and thence out ot' the separator through a pipe 16. rllhrough this pipe the Water iioWs out of the boiler into a pipe 17 and thence into a trap 18 Twhere, by means of a valve 19 operated by a float 2G, the Water is passed out through a pipe 21 in an ordinary manner. lhere a. number ot sections ot separators are used, such as the sections 22, 23, and 2% ot Fig. 8, a drain pipe 16 is used tor each section and they all connect With a common drain pipe 25. Normally the 'drain pipes 25 and 17 and the receiver 18 are filled with steam or air. TVhen Water begins to flow down the pipes 16 toward the receiver 1S the displaced gas must go somewhere. It there is no vent the gas must flow counter-current to the liquid and thus interfere With the How of liquid.

To prevent this tendency ot the drain pipes 1%26. Serial No. 107,945. Y

to clog, 1 provide a vent pipe 26 which projects upwardly into the water chamber 15 of the separator to adjacent the upper Wall thereof and is connected, by means ot' pipes 27 and 28, with the trap, as indicated. 1n this manner the steam which tends to accumulate in the trap is free to pass out from the trap through the vent pipes back into the Water chamber 15 ot the separator.

lNith this arrangement there is no obstruction in the drain pipes owing to any entrained steam or air, and the capacity thereot is very greatly increased, so that the size ot these pipes may be very materially decreased tor the same separator capacity. At the same time, as the flow of Water into the steam trap is continuous and unintertered with, the iioiv therein, under normal Working operations, substantially uniform and the tendency is for the valve 19 to be opened iore continuously and uniformly, so that the capacities of the trap and the pipe 21 are also very materially increased.

Furthermore, there is no bach HOW of the entrained steam :trom the drain pipe into the Water chamber ot the puriiier. Such back tioiv not only materially disturbs the Water in the chamber, but the steam carries with it entrained Water. The vent pipe also tends to equalize the pressures in the Water chambers when there are several independent sections ot separators connected to the same drain pipe, and this much reduces the tendency ot local currents ot steam or water to iiow through the drain pipes and Water chambers.

claim as my invention:

1. The combination ot a steam separator and a stationary steam trap, said separator having a steam chamber and a Water chamber, and a steam outlet communicating with said steam chamber, a partition separating said chambers, and a drain pipe and a vent pipe continuously operatively connectingT said Water chamber with sait trap, said vent pipe outlet in said Water chamber being below said steam outlet.

2. The combination ot a steam separator and a stationary steam t-rap, said separator having a steam chamber and a Water chamber, a partition separating said chambers, a. drain pipe and a vent pipe continuously operatively connecting said Water chamber with said trap, said separator having a dry steam outlet in said steam chamber, and baliies mounted in said separator between said chambers, the outlet of said' vent pipe in said Water Chamber being` beloW said steam cham# bei'. v

Y by. The eombination'of a steam Separator and akst'eam trap, said separator having a steam Chamber and a Water chamber, a partition separating Said chambers, and a, drain -pipe and a` vent pipe continuously operaf lO tively connecting said Water chamber .With

Y said tiap, the endof said Vent pipe projecting intol said Water chamber to the upper portion separator mounted in Vsaid boiler, a steam trap mounted outside of said boiler, said separator having a steam inlet and a steam outlet, afwatei1 chamber and a steam cha-1nbei, tWo pipes continuously,operatively eonneeting Said Water chamber With said trap, a partition mounted between Said chambers, and steam drying baflles mounted in said separator between said Water' chamber and said inlet and outlet.

In testimony whereof, I hereunto set my hand;
